摘要: 根据蜡叶标本、文献资料及实地调查,整理出浙江野生苦苣苔科Gesneriaceae植物11属20种,比《浙江植物志》记载的9属16种增加了2个新记录属(全唇苣苔属Deinocheilos,小花苣苔属Chiritopsis)及4个新记录种(江唇西全苣苔Deinocheilos jiangxiense,休宁小花苣苔Chiritobsis xiuningensis,蚂蝗七Chirita fimbrisepala,长瓣马铃苣苔Oreocharis auricular)。根据地形地貌、生境、母岩土壤、山脉等分析显示,该科植物在浙江省内广泛分布,多分布在西部及南部丘陵山区,有近半数种喜生于石灰岩山地,且不同种之间生境存在较大差异。该科植物可应用于阴湿花坛、林下地被、假山等园林空间。应优先对珍稀特有及观赏价值高的种类开展生物学、生态学方面的研究,并采用快繁技术进行扩繁,对珍稀种类应试行野外回归工作,以扩大种群数量。建议对一些特有珍稀种类的分布区域或分布较集中的区域划定保护小区。表2参14Abstract: This study conducted in Zhejiang Province arranged Gesneriaceae plants into 11 genera which included 20 species of Gesneriaceae wildling found in herbariums,documents,and investigations. Included were two newly recorded genera:Deinocheilos and Chiritopsis,as well as four newly recorded species not previously recorded as Flora of Zhejiang:Deinocheilos jiangxiense,Chiritopsis xiuningensis,Chirita fimbrisepala,and Oreocharis auricula. This research analyzed the distribution of the characteristics of these plants in Zhejiang Province on the basis of topography,habitat,soils,and mountains. Results showed that these plants were widespread across the province with most of them located in the western and southern hills and with nearly half of the species preferring limestone soils. Differences in habitat among different species were also found. Plants of this family could be grown in damp flower-beds,as groundcover,with rockeries,and in other garden spaces. For protection,priority for conducting biological and ecological research using rapid propagation techniques to expand the population,should be given to rare,endemic species as well as to those with high ornamental value. Wild regression of rare species should also be tried. To help demarcate protected areas,suggestions could be offered for distribution of some endemic and rare species found in relatively concentrated areas. [Ch,2 tab. 14 ref.]
